dBAviktning
dBAviktning, often written as dB(A) or dBA, refers to a sound level measured with A-weighting. A-weighting is a standard frequency weighting used in acoustics to approximate the sensitivity of the human ear, so dBAviktning expresses perceived loudness rather than the raw sound pressure.
The A-weighting curve adjusts the spectrum by attenuating low frequencies and reducing very high frequencies, while
Measurement and standards: Modern sound level meters apply the A-weighting filter in real time and report values
Applications and limitations: dBAviktning is widely used in occupational health, environmental noise assessments, building acoustics, and
